1 - Keep your wishlist formatted like the below, a band a line. It's easier for me to work with than comma separated (ie band a, band b, band c, band d)
2 - Happy for people to make additions to their wishlists! I just ask that you make them as a new post, as I cannot detect if you've gone back and edited your initial post
3 - No rules on numbers (you can make 1 request, you can make a thousand!) but please don't "vote stuff" by requesting the same band multiple times. That's not cool.
4 - No limits on what you request either! You want to request Iron Maiden even though there is zero chance of them doing 70K? Go for it!
5 - No 'deadline' either - I'll keep compiling the data right up until the date of sailing, 2021. I will at some point "formally" submit the list to the skipper though (not sure when as we don't have sail dates yet)

Updated a bunch because I made my initial wish list late last year. Plus I forgot to go through bands that were out due to playing in 2019. Throw 1349, Benediction, Be'Lakor, Carcass, Crowbar, Dying Fetus, Exhumed, Inquisition (if people are over his shit), Immolation, Katatonia, Malevolent Creation, Meshuggah, Secrets of the Moon, Swashbuckle (just for a laugh), Vesania on mine also. Plenty of other bands that I would enjoy seeing, but not so much to put on a wish list.
